Description

Technical Field

[0001] This utility model relates to the field of crane boom processing technology, and in particular to a machining fixture for the end face of a crane hydraulic synchronous boom. Background Technology

[0002] During the machining of crane booms, positioning and clamping are required. Existing clamping methods for crane booms generally use general-purpose fixtures, which are not suitable for positioning and clamping according to the size of the crane boom. This results in low efficiency in crane boom clamping operations. When machining the end face of the crane boom, existing fixed-structure fixtures cannot adjust the position of the clamped crane boom, leading to poor machining flexibility. Repeated clamping of the crane boom is required to complete the machining of the end face, resulting in low machining efficiency and poor practicality. To address these issues, we propose a new end face machining fixture for a hydraulic synchronous crane boom. Utility Model Content
